Info

confidence the extent to which gas is an issue. The local planning authority will expect to receive gas monitoring data collected from appropriate locations on at least six separate occasions over a minimum period of twelve months. Monitoring should be targeted to days when the atmospheric pressure is low and falling, as these are the optimal conditions for gas migration. Further guidance on site investigation can be obtained from the documents listed at the end of this appendix. Cleaning up contamination (Remediation) Where the investigation phase indicates no significant contamination or gas problem in relation to the proposed end use, the developer will not be required to undertake remedial works. This is consistent with the UK Government's "suitable for use" approach to cleaning up historic pollution. However, the developer will need to have a contingency plan should the construction phase reveal any contamination, which must be immediately reported to the Council’s Environmental Health service on 01628 683516. Where the investigation reveals contamination and/or gas, the developer must develop a detailed scheme of remedial works to be taken to avoid any risk arising when the site is developed or occupied. Where ground gases are an issue the scheme must detail the precise methods proposed to prevent the build up of gaseous material within the proposed buildings and under car park areas, arising from the site or adjacent land. The development shall only be constructed in accordance with the agreed scheme. Any equipment to prevent the build up of gaseous conditions must be fully installed and operating prior to occupation of the development, and thereafter shall be maintained in use at all times and monitored. The Council may require a programme of further monitoring to be undertaken. On completion of the works the developer must provide written confirmation that all the remedial works were completed in accordance with the scheme.
